Metabolite Identification
Common NamePalmitoyl Ara-C
DescriptionN-{1-[3,4-dihydroxy-5-(hydroxymethyl)oxolan-2-yl]-2-hydroxy-1,4-dihydropyrimidin-4-ylidene}hexadecanamide belongs to the class of organic compounds known as pyrimidine nucleosides. Pyrimidine nucleosides are compounds comprising a pyrimidine base attached to a ribosyl or deoxyribosyl moiety. Based on a literature review very few articles have been published on N-{1-[3,4-dihydroxy-5-(hydroxymethyl)oxolan-2-yl]-2-hydroxy-1,4-dihydropyrimidin-4-ylidene}hexadecanamide. This compound has been identified in human blood as reported by (PMID: 31557052 ). Palmitoyl ara-c is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Palmitoyl Ara-C is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
